Equity [Abstract]
Equity	7. Equity *2011 Financings* On April 20, 2011, the Company completed an underwritten public offering of 11,950,000 units at a price to the public of $1.00 per unit for gross proceeds of approximately $12 million (the “April 2011 Offering”). Each unit consisted of one share of common stock and a warrant to purchase one share of common stock at an exercise price of $1.00 per share. The shares of common stock and warrants were immediately separable and no separate units were issued. The warrants are exercisable beginning one year and one day from the date of issuance, but only if the Company’s stockholders approve an increase in the number of authorized shares of common stock of the Company, and expire on the sixth anniversary of the date of issuance. Net proceeds, after underwriting discounts and commissions and other offering expenses, were approximately $10.9 million. In connection with the April financing, the Company agreed to hold a stockholders meeting no later than July 31, 2011 in order to seek stockholder approval for an amendment to the Company’s Amended and Restated Certificate of Incorporation to increase the authorized number of shares or our common stock. The Board of Directors of the Company subsequently adopted an amendment to increase the authorized shares of common stock to 125,000,000, which was presented to and approved by the stockholders of the Company at the 2011 Annual Meeting of Stockholders held on July 15, 2011. On March 4, 2011, the Company closed an underwritten public offering of 6,000,000 units at a price to the public of $1.35 per unit for gross proceeds of $8.1 million (the“March 2011 Offering”). The offering provided approximately $7.3 million to the Company after deducting the underwriting discounts and commissions and offering expenses. Each unit consists of (i) one share of common stock, (ii) a thirteen-month warrant to purchase 0.50 of a share of common stock at an exercise price of $1.70 per share (subject to anti-dilution adjustment) and (iii) a five-year warrant to purchase 0.50 of a share of common stock at an exercise price of $1.87 per share (subject to anti-dilution adjustment). On April 15, 2011, the holders of outstanding warrants issued in the March 2011 Offering to purchase an aggregate of 3,450,000 shares of common stock agreed to exchange such warrants for warrants exercisable for the same number of shares as those being exchanged, but otherwise on the same terms of the warrants sold in the Company’s April 2011 financing. Prior to the exchange, the Company recorded a decrease in fair value of $1,000,000 related to the exchanged warrants. Upon the exchange, the Company recorded a loss of $900,000, which represented the difference between the adjusted fair value of the March 2011 warrants as compared to the fair value of the April 2011 warrants received in the exchange. As a result of a subsequent offering that was completed on April 15, 2011, the exercise price of the remaining 2,550,000 outstanding warrants sold in the March 2011 Offering was reduced to $1.00 per share as a result of the anti-dilution adjustment. *Warrants Potentially Settleable in Cash* Certain warrants issued in connection with a registered direct stock offering on August 3, 2009 (the “2009 Offering”) were determined not to be indexed to the Company’s common stock as they are potentially settleable in cash. The fair value of the warrants at the dates of issuance totaling $2,863,000 was recorded as a liability and a cost of equity and was determined by the Black-Scholes option pricing model. Due to the fact that the Company has limited trading history, the Company’s expected stock volatility assumption is based on a combination of implied volatilities of similar entities whose shares or options are publicly traded. The Company used a weighted average expected stock volatility of 122.69%. The expected life assumption is based on the contract term of five years. The dividend yield of zero is based on the fact that the Company has no present intention to pay cash dividends. The risk free rate of 1.72% used for the warrants is equal to the zero coupon rate in effect at the time of the grant. The decrease in the fair value of the warrants from the date of issuance to June 30, 2011 is $2,718,000, of which $1,799,000 has been included in other income and expense in the accompanying condensed statements of expenses for the six months ended June 30, 2011. The fair value of the warrants at June 30, 2011 of $144,000 is included as a current liability in the accompanying balance sheets and was determined by the Black-Scholes option pricing model. Due to the fact that the Company has limited trading history, the Company’s expected stock volatility assumption is based on a combination of implied volatilities of similar entities whose shares or options are publicly traded. The Company used a weighted average expected stock volatility of 74.52%. The expected life assumption is based on the remaining contract term of 3.1 years. The dividend yield of zero is based on the fact that we have no present intention to pay cash dividends. The risk free rate of 0.81% used for the warrants is equal to the zero coupon rate in effect on the date of the re-measurement. Certain warrants issued in connection with the March 22, 2010 stock offering (the “2010 Offering”) were determined not to be indexed to the Company’s common stock as they are potentially settleable in cash. The fair value of the warrants at the dates of issuance totaling $2,466,000 was recorded as a liability and a cost of equity and was determined using the Black-Scholes option pricing model. Due to the fact that the Company has limited trading history, our expected stock volatility assumption is based on a combination of implied volatilities of similar entities whose shares or options are publicly traded. The Company used a weighted average expected stock volatility of 119.49%. The expected life assumption is based on the contract term of 6.5 years. The dividend yield of zero is based on the fact that we have no present intention to pay cash dividends. The risk free rate of 3.22% used for the warrants is equal to the zero coupon rate in effect at the time of the grant. The decrease in the fair value of the warrants from date of issuance to June 30, 2011 is $2,245,000, of which $974,000 has been included in other income and expense in the accompanying condensed statements of expenses for the six months ended June 30, 2011. The fair value of the warrants at June 30, 2011 of $221,000 is included as a current liability in the accompanying balance sheets and was determined by the Black-Scholes option pricing model. Due to the fact that the Company has limited trading history, the Company’s expected stock volatility assumption is based on a combination of implied volatilities of similar entities whose shares or options are publicly traded. The Company used a weighted average expected stock volatility of 74.52%. The expected life assumption is based on the remaining contract term of 5.25 years. The dividend yield of zero is based on the fact that the Company has no present intention to pay cash dividends. The risk free rate of 1.76% used for the warrants is equal to the zero coupon rate in effect on the date of the re-measurement. The thirteen-month and five-year warrants issued in connection with the March 2011 Offering were determined not to be indexed to the Company’s common stock as they are potentially settleable in cash. The fair value of the remaining 2,550,000 warrants at the date of issuance totaling $1,790,000 was recorded as a liability and a cost of equity and was determined using the Black-Scholes option pricing model. Due to the fact that the Company has limited trading history, the Company expected stock volatility assumption is based on a combination of implied volatilities of similar entities whose shares or options are publicly traded.

The dividend yield of zero is based on the fact that we have no present intention to pay cash dividends. The risk free rate of 0.26% used for the thirteen-month warrants and 2.17% used for the five-year warrants is equal to the zero coupon rate in effect at the time of the grant. The decrease in the fair value of the warrants from date of issuance to June 30, 2011 of $745,000 has been included in other income and expense in the accompanying condensed statements of expenses for the six months ended June 30, 2011. The fair value of the warrants at June 30, 2011 of $1,050,000 is included as a current liability in the accompanying balance sheets and was determined using the Black-Scholes option pricing model. Due to the fact that the Company has limited trading history, the Company’s expected stock volatility assumption is based on a combination of implied volatilities of similar entities whose shares or options are publicly traded. The Company used a weighted average expected stock volatility of 74.52%. The expected life assumption is based on the remaining contract term of one year used for the thirteen-month warrants and 4.7 years used for the five- year warrants. The dividend yield of zero is based on the fact that the Company has no present intention to pay cash dividends. The risk free rate of 0.19% used for the thirteen-month warrants and 1.76% used for the five-year warrants is equal to the zero coupon rate in effect on the date of the re-measurement. The warrants issued in connection with the April 2011 Offering, including the warrants issued in exchanged for the March 2011 warrants, were determined not to be indexed to the Company’s common stock as they are potentially settleable in cash. The fair value of the warrants at the dates of issuance totaling $11,442,000 was recorded as a liability and a cost of equity and was determined using the Black-Scholes option pricing model. Due to the fact that the Company has limited trading history, the Company’s expected stock volatility assumption is based on a combination of implied volatilities of similar entities whose shares or options are publically traded. The Company used a weighted average expected stock volatility of 99.04%. The expected life assumption is based on the contract term of 7.0 years. The dividend yield of zero is based on the fact that we have no present intention to pay cash dividends. The risk free rate of 2.81% used for the warrants is equal to the zero coupon rate in effect at the time of the grant. The decrease in the fair value of the warrants from date of issuance to June 30, 2011 is $1,875,000, of which all has been included in other income and expense in the accompanying condensed statements of expenses for the six months ended June 30, 2011.

The risk free rate of 2.5% used for the warrants is equal to the zero coupon rate in effect on the date of the re-measurement. Additionally, in connection with the previously discussed exchange, the Company recorded a loss of approximately $900,000 which accounts for the remaining change in value during the period. *Stock Options Modified* On April 14, 2011, all of the Company’s directors and certain of the Company’s executive officers executed agreements with the Company under which they agreed that none of their outstanding stock options will be exercisable unless and until the Company increases the number of authorized shares of common stock to a number that is sufficient to permit the exercise or conversion in full of all then outstanding options of the Company (including their stock options), warrants and other securities of the Company that are convertible into shares of common stock. An aggregate of 3,498,256 option shares are covered by these agreements. For accounting purposes, the agreement of all of the Company’s directors and certain executive officers to place restrictions of the exercisability of their options is treated as a modification of their options resulting in the reclassification of the options from equity to a liability. In connection with the modification, the Company will recognize compensation cost equal to the greater of (a) the grant date fair value of the original equity award plus an incremental cost associated with the modification or (b) the fair value of the modified award when it is settled. As of June 30, 2011, the Company recorded a liability of $682,000 representing the fair value of the vested portion of these options with a corresponding decrease of $674,000 to additional paid in capital for previously recognized stock compensation expense and a $7,000 charge to operations.

2011 Financings

On April 20, 2011, the Company completed an underwritten public offering of 11,950,000 units at a price to the public of $1.00 per unit for gross proceeds of approximately $12 million (the “April 2011 Offering”). Each unit consisted of one share of common stock and a warrant to purchase one share of common stock at an exercise price of $1.00 per share. The shares of common stock and warrants were immediately separable and no separate units were issued. The warrants are exercisable beginning one year and one day from the date of issuance, but only if the Company’s stockholders approve an increase in the number of authorized shares of common stock of the Company, and expire on the sixth anniversary of the date of issuance. Net proceeds, after underwriting discounts and commissions and other offering expenses, were approximately $10.9 million. In connection with the April financing, the Company agreed to hold a stockholders meeting no later than July 31, 2011 in order to seek stockholder approval for an amendment to the Company’s Amended and Restated Certificate of Incorporation to increase the authorized number of shares or our common stock. The Board of Directors of the Company subsequently adopted an amendment to increase the authorized shares of common stock to 125,000,000, which was presented to and approved by the stockholders of the Company at the 2011 Annual Meeting of Stockholders held on July 15, 2011.

On March 4, 2011, the Company closed an underwritten public offering of 6,000,000 units at a price to the public of $1.35 per unit for gross proceeds of $8.1 million (the“March 2011 Offering”). The offering provided approximately $7.3 million to the Company after deducting the underwriting discounts and commissions and offering expenses. Each unit consists of (i) one share of common stock, (ii) a thirteen-month warrant to purchase 0.50 of a share of common stock at an exercise price of $1.70 per share (subject to anti-dilution adjustment) and (iii) a five-year warrant to purchase 0.50 of a share of common stock at an exercise price of $1.87 per share (subject to anti-dilution adjustment). On April 15, 2011, the holders of outstanding warrants issued in the March 2011 Offering to purchase an aggregate of 3,450,000 shares of common stock agreed to exchange such warrants for warrants exercisable for the same number of shares as those being exchanged, but otherwise on the same terms of the warrants sold in the Company’s April 2011 financing. Prior to the exchange, the Company recorded a decrease in fair value of $1,000,000 related to the exchanged warrants. Upon the exchange, the Company recorded a loss of $900,000, which represented the difference between the adjusted fair value of the March 2011 warrants as compared to the fair value of the April 2011 warrants received in the exchange. As a result of a subsequent offering that was completed on April 15, 2011, the exercise price of the remaining 2,550,000 outstanding warrants sold in the March 2011 Offering was reduced to $1.00 per share as a result of the anti-dilution adjustment.

Stock Options Modified

On April 14, 2011, all of the Company’s directors and certain of the Company’s executive officers executed agreements with the Company under which they agreed that none of their outstanding stock options will be exercisable unless and until the Company increases the number of authorized shares of common stock to a number that is sufficient to permit the exercise or conversion in full of all then outstanding options of the Company (including their stock options), warrants and other securities of the Company that are convertible into shares of common stock.

In connection with the modification, the Company will recognize compensation cost equal to the greater of (a) the grant date fair value of the original equity award plus an incremental cost associated with the modification or (b) the fair value of the modified award when it is settled. As of June 30, 2011, the Company recorded a liability of $682,000 representing the fair value of the vested portion of these options with a corresponding decrease of $674,000 to additional paid in capital for previously recognized stock compensation expense and a $7,000 charge to operations.
